Maintenance Architecture
For best OSM performance, no more than 10 servers should be included within one
subnet.
Because all servers are shipped with the same preconfigured IP addresses for MSP0,
MSP1, $ZTCP0, and $ZTCP1, you must change these IP addresses for the second
and subsequent servers before you can add them to the LAN.
You must change the preconfigured IP addresses of the second and subsequent
system consoles before you can add them to the LAN.
Maintenance Architecture
This simplified illustration shows the three elements of the maintenance architecture
plus the OSM maintenance console applications:
As this illustration shows, the OSM console connects to a closed and private service
LAN, connecting these modules together via a maintenance switch (a ProCurve 2524):
•
Processor switch (p-switch)
•
I/O adapter module (IOAM)
